Gulfstream TRS

I've been trying for awhile to figure out what type of trunking system the frequencies licensed to Gulfstream Aerospace for a business trunking system were part of, but I never heard anything on them even scanning them conventionally. I'll chalk that up to just not being in the area at the right time, but I finally heard something today. It seems that it is an LTR system, just not a very busy one. I only heard two talkgroups active, one of them only once. As such it was hard to determine an LCN for the frequencies (right now I'm trying them in numerical order).
